SHUTTER-FASTE NE R.

T 0 all whom it may concern:

Be it known that I, HILLIARD FRANCIS CHEEITZBERG, a citizen of the United States, and a resident of Winston Salem, in the county of Forsyth and State of North Carolina, have invented a new and Improved Shutter-Fastener, of which the following is a full, clear, and exact description.

This invention relates to shutter fasteners, and more especially to fasteners for shutters, window blinds, and the like, by means 0f which the latter can be securely looked in closed position, and which are operable from the inside only, of the window.

An object of the invention is to provide a simple, strong and durable fastener by means of which the shutter, door or the like can be securely locked in position, and which cannot be released from the outside without breaking the shutter or other closure, or the frame of the same.

A further object of the invention is to provide a device of the class described which automatically engages the catch of the shutter or other closure to lock the same in position, and which is held in a normal operative position gravitationally.

The invention consists of novel features and parts and combinations of the same, all of which will be more fully described hereinafter and particularly set forth in the claims.

Reference is to be had to theaccompanying drawings forming a part of this specification, in which similar characters of reference indicate corresponding parts throughout the views, and in which v Figure 1 is a transverse section of a portion of a window frame and a shutter showing my invention ap lied thereto; Eig. 2 is a perspective view o a lower portion of a window frame with my fastener mounted in osition thereupon and showing parts of the fastener in dotted outlines, Fig. 3 is an enlarged perspective view of a part of the device, showing a portion broken away, and Fig. 4 is an enlarged transverse section showing certain details of construction.

Before proceeding to a more detailed explanation of my invention, it should be understood that the same is particularly useful in connection with shutters or window blinds but that it can also be advantageously applied to closures of different kinds for example, to swinging doors or windows. If a closure, such as a shutter, is to be effective in Specification of Letters Patent.

Patented April 14, 1908.

Application filed December 3, 1907. Serial No. 404,914.

preventing unauthorized ingress into a building it must have means for locking it ina closed position, which are of such a nature that they cannot be released from the outside. My fastener answers this purpose fully, and can only be operated legitimately from the inside of the window. To release the fastener from the outside, it is necessary to break the shutter or the window frame. The fastener of my invention is operated by merely swinging the shutter into a closed position, the retaining member of the device engaging a catch carried by the shutter for the purpose.

Referring more particularly to the drawings, 1 represents the framing or trim of a window of the usual type; the shutters 2 are mounted to swing at the sides of the window frame by means of hinges and are arranged to swing toward each other when they are being closed. The shutters may be of any preferred or common form, and operate in the usual manner. One of the shutters has a lateral flange or rib 3, which engages at the outer side of the other shutter to hold the latter in position. Consequently it is necessary to lock the first shutter only, to hold both closed.

A hook or catch 4, having an attaching plate 5, is secured near the inner lower edge of the first shutter by means of screws or in any other suitable manner. By the first shutter is meant the one which has the flange 3 serving to hold the other shutter in a closed position. The hook 4 has a shoulder 6 and a rounded nose 7, for a purpose which will appear hereinafter.

A recess 8 is fashioned in the outer face of the lower window frame member, and is formed to receive a case 9. The latter at the opposite ends has flanges 1() provided lwith openings 11 therethrough, adapted to receive screws or the like serving to mount the case in position. Preferably the flanges 10 are counter-sunk in suitable recesses adjacent to the recess 8. The case 9 may be formed from cast metal or any other suitable material, and at the outer wall has an opening 12 to permit the entrance into the case of the catch 4. The inner wall of the case is cut away, as is shown most clearly in Eig. 3. A swinging member 13 is movably mounted within the case by means of a pivot pin 14. At the end remote from the pivot pin 14, the member 13 is beveled outwardly to permit the member to be displaced when the beveled portion is engaged by the rounded nose 7 of the catch; to permit the catch to move into a position such that it projects inwardly beyond the member 13 and engages at the inner face of the latter with the shoulder 6. When in this position, as is shown in Fig. 3, the shutter is securely locked by means of the engagement of the swinging member with the catch. At the under side of the member 13 is a rounded, edge recess 15, Adjacent to the latter is arranged a head 1.6 having a lateral extension or cam portion 17. rIhe .head has an extension 18 pivotally mounted in a suitable opening 19 of the case.

A rod 20, preferably of angular section has theend located in a suitably formed opening 21 of the head. The rod extends through an elongated opening or bore 22, fashioned in the lower part of the window frame, and eX- tends through a sleeve 23, arranged in a registering opening at the inner side of the window frame. The .end of the rod is formed into a handle 24, by means of which it can be conveniently manipulated. rI`he sleeve 23 has a face plate 25, secured in position at the window frame by means of screws or in any other suitable manner. In the normal position ofthe fastener parts, the cam 17 is so disposed that the member 13 gravitationally assumes a depressed position. Vhen the shutter is swung inwardly, Athe hook or catch passes through the opening in the wall of the case and slides under the member, displacing the latter upwardly by the engagement of the `rounded nose of the catch with the rounded or beveled portion of the member. The latter has extensions 13a at the lower edge, which in its depressed position, hold the beveled portion slightly above the bottom ofthe case. As the shoulder 6 passes inwardly beyond the member 13, the latter returns to its depressed position, as is shown most clearly in Fig. 3. The shoulder 6 then engages the inner face of the member, and the hook is locked against a return, thereby holding the shutter closed. When it is desired to release the shutter, the rod 20 is turned so that the cam 17 engages the cam recess 15, to swing the member upon its pivot to release it from the catch, leaving the shutter free to be y swung outwardly.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. A fastener, comprising a catch adapted to be mounted upon a shutter, a holding member adapted to be arranged upon a window frame and formed to engage said catch to lock the shutter in a closed position, said member being gravitationally held in an operative position, and rotatable means having a cam-like action and adapted to displace said member to release said catch.

21 A fastener comprising a catch adapted to be mounted upon a shutter, a movable holding member adapted to be arranged upon a window frame and formed to engage said catch to lock the shutter in a closed position, said member being gravitationally held in a normal operative position, and rotatable means for displacing said member to release said catch, said means being independent of said member and being adapted to be actuated to engage the same.

8. A fastener comprising a catch adapted to be mounted upon a shutter, a pivoted member adapted to be arranged in an opening of a Window frame and presenting an edge for engaging said catch to lock the shutter in a closed position, said pivoted member being gravitationally held in an operative position and being arranged to be displaced by said catch to permit the same to engage said edge, and rotatable means operable from the inner side of the window frame for engaging said member to displace the same into an inoperative position.

4. A fastener comprising a catch adapted to be mounted upon a shutter, a swinging member adapted to be arranged in an opening of the window frame and formed to engage said catch to lock the shutter in a closed position, said swinging member being gravitationally held in a normal operative osition said catch and said member beinfr P 1 e formed to permit the former to displace said member when said catch is moved into a locking position, a cam arranged to displace said member into an operative position, and means for operating said cam from one side of the window frame.

5. A fastener, comprising a catch adapted to be mounted upon a shutter, a holding member adapted to be mounted upon a window frame and formed to engage said catch to lock the shutter in a closed position, said member being arranged to swing transversely of said catch, and means for displacing said member to release said catch.

6. A fastener, comprising a catch adapted to be mounted upon a shutter, a holding member adapted to be mounted upon a window frame and formed to engage said catch to lock the shutter in a closed position, said member being gravitationally heldin a normal position and being arranged to swingv transversely of said catch, and means independent of said member and serving to operate the same to release said catch.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
